Definition
The act of controlling an aircraft's attitude, altitude, heading, and flight path solely by reference to the cockpit instruments, without using outside visual cues such as the horizon or ground features.
Plain English
Flying the aircraft by reading the gauges instead of looking out the window. The pilot trusts the instruments to know which way is up, where the aircraft is heading, and how fast it is climbing or descending.
Context Anchor
Encountered at the start of instrument training, especially when learning to keep the aircraft under control in clouds, haze, darkness, or any situation where outside visual cues are limited.
Derivation
Instrument comes from Latin instrumentum, meaning a tool or piece of equipment used to do something. In aviation, the instruments are the tools that show the pilot what the aircraft is doing when the outside view is not enough.
Why Pilots Care
Enables continued safe flight when clouds, fog, haze, or darkness remove visual references outside the aircraft.
Intuition Check
Instrument flying does not mean simply flying an airplane that has instruments. It means using those instruments as the main reference for controlling the airplane when outside cues are not enough.
Example Sentence 1
Once the aircraft entered the cloud layer, the pilot transitioned to instrument flying and held heading and altitude by reference to the attitude indicator and altimeter.
Example Sentence 2
Instrument flying allowed the pilot to continue the approach after entering the cloud layer.
